According to KHOU, Davis' father, Marquis Davis Sr., said his son is innocent of murder.

Davis went on to say that the friend then "forced" his son to shoot up and rob the House of Pies, according to the TV station.

The younger Davis – known by the nickname "Dootie" – has a record of arrests dating back to at least 2010, when he was a juvenile offender detained by the Texas Youth Commission, court records show.
